【発明の属する技術分野】
本発明は、ダニ誘引剤、ダニ誘引剤に含まれるダニ誘引成分を利用したダニ誘引捕獲材及びダニ誘引方法に関する。
【０００２】
【従来の技術】
近年、建築技術の進歩に伴う住居の高い密閉性、エアコンの普及およびカーペット類の敷設等により、ダニの生息に好条件の環境が整えられ、ダニの繁殖を助長しているのが実状である。ダニは特に布団などの寝具やカーペット、ソファーに多く棲息しており、気管支喘息、アレルギー鼻炎等のアレルギー性疾患や、皮膚炎の原因となるため、効果的な駆除が要望されている。
【０００３】
ダニの駆除の方法として、殺ダニ剤を散布したり、天日干しや掃除機等による物理的に駆除する方法があげられる。殺ダニ剤が用いられる場合は、寝具等には安全性上好ましくなく、またダニの死骸等が依然としてダニの棲息している場所、たとえば、寝具やカーペット等にアレルゲンとして残されるという問題がある。また、単なる物理的駆除方法では、多大な労力を要する。
【０００４】
そこで、この問題を解決できるダニ誘引剤やダニ捕獲材が検討されている（特許文献１、特許文献２）。ダニ誘引剤の有効成分としては、特許文献１に炭素数４〜１８の直鎖脂肪酸が開示され、特許文献２に分岐脂肪族アルデヒドであるシトラールが開示されている。
しかしながら、上記文献に記載された誘引剤は、誘引効果が必ずしも充分とはいえなかった。

In recent years, due to the high hermeticity of dwellings, the spread of air conditioners, and the laying of carpets, etc., due to the progress of construction technology, favorable conditions for habitat of mites have been prepared, and it is a fact that the mite is breeding. . Mites in particular live in beddings such as futons, carpets and sofas, and cause allergic diseases such as bronchial asthma and allergic rhinitis, and dermatitis. Therefore, effective control of mites is required.
[0003]
Examples of a method of exterminating mites include a method of spraying an acaricide or physically exterminating with a sun dryer or a vacuum cleaner. When a miticide is used, there is a problem in that bedding and the like are not preferable in terms of safety, and there is a problem that a dead body of a tick is left as an allergen in a place where a tick still inhabits, for example, bedding or a carpet. Also, a simple physical extermination method requires a great deal of labor.
[0004]
Therefore, mite attractants and tick trapping materials that can solve this problem have been studied (Patent Documents 1 and 2). As an active ingredient of the tick attractant, Patent Literature 1 discloses a linear fatty acid having 4 to 18 carbon atoms, and Patent Literature 2 discloses citral, which is a branched aliphatic aldehyde.
However, the attractants described in the above-mentioned documents did not necessarily have sufficient attraction effects.

(Example 2) A nonwoven fabric of the same size was stuck to an adhesive tape of 5 x 5 cm in size of a capture sheet, and 1 µL of an attracting composition having the following formulation was impregnated to obtain a mite capture sheet. In Comparative Examples, stearic acid was used. Using this tick capturing sheet, a capturing sheet to which no attractant was applied was placed in the control area, the capturing sheet was replaced with black paper by the method of Example 1, and after 24 hours, the mites captured by the adhesive tape were removed. Counted by microscope.
<Attractive composition>
Nonanal 60 parts by mass Limonene 40 parts by mass As shown in Table 2, more mite was captured on the sheet to which the attractant was applied than the sheet of the comparative example, and the usefulness of the present invention was recognized. In addition, although a small number of mites were collected on the capture sheet in the control plot, it means that the state of the test and test mites was normal.

Example 3 Dust A dust was prepared according to the following formulation.
Sodium sulfate 60 parts by mass Silica 39.8 parts by mass Octanal 0.1 parts by mass Dodecanal 0.1 parts by mass
Example 4 Dust A dust was prepared according to the following formulation.
Silica anhydride 5 parts by weight Talc 85 parts by weight Heptanal 1 part by weight Lemon oil 9 parts by weight
Example 5 Granules Granules were produced according to the following formulation.
Fluorite RM-20 (manufactured by Tokuyama) 70 parts by mass t-2-decenal 5 parts by mass decanal 5 parts by mass Orange oil 20 parts by mass
(Example 6) Oil solution An oil solution was manufactured according to the following formulation.
Isopropyl alcohol 98 parts by mass t-2-undecenal 2 parts by mass
【The invention's effect】
The tick attractant according to the present invention contains a novel tick attractant component and has a high attracting effect on mites. Therefore, ticks can be collected at a certain location, and intensive mite control can be achieved. Further, the tick-attracting trapping material and tick-attracting method according to the present invention uses the tick-attracting agent according to the present invention having a high attraction, so that the mites inhabiting the bedding and the like are effectively induced to a predetermined place, It is possible to exterminate ticks intensively without leaving dead ticks that become allergic substances on bedding and the like.
